The document outlines procedures for various types of mechanical installations. It discusses common installation procedures such as material management and quality control. It also describes procedures for rotating equipment installation, including foundation preparation, machinery alignment, and start-up. Static equipment such as pressure vessels and tanks are also addressed. The document provides details on assessing vessels and tanks during installation. Finally, it discusses piping system fabrication and installation, including welding processes and leak testing.

1. 1
Mechanical Installation
1) Common procedures
 Material management (Purchase orders, storage facilities, control procedures,
traceability, spare parts)
 Identification of Non conformities
 Quality audit
 Mechanical Completion report
2) Rotating equipment Installation
 Pre-installation and equipment preservation measures
 Foundation and anchor bolts
 Base plate and Soleplate preparation
 Epoxy or cement based grout (if applicable)
 Machinery alignment
 Pre-operational check
 Preparation and Start up
3) Static equipment installation
a) Pressure vessels
 Assessment of discontinuity stress on the vessel head to shell joints
 Assessment of nozzle attachments and nozzle opening cut into shell
 Assessment welded lifting lugs and hooks
 Assessment wind loads bending stresses around the welds at the base, especially
vertical column type vessels
 Assessment of Corrosion, mechanical damage, cracks and profile distortion
 Assessment out of roundness (Bulging)
 Assessment of longitudinal weld seams (Peaking)
 Hydrostatic testing
b) Additional for Tanks
 Material consideration
 Corrosion prevention
 Tank foundation, roofs and fire protection
 Tank settlement

4) Fabrication and Installation of piping system
 Assessment of Installation drawings and tolerances
 Erection planning
 Delivering a Cold spring (gap at some final closure weld and anchors on both side
of the joint to preserve alignment during welding)
 Joint alignment
 Installation of Mechanical joints (threaded, flanged)
 Installation of pipe support
 Cutting and bevelling
 Forming and Bending
 Welding processes (Shield Metal Arc, Submerged Arc, Gas Shield Arc (Gas
tungsten arc, gas metal arc, flux core arc))
 Leak testing
5) Additional points for HVAC and Refrigeration systems Installations and commissioning
 Evacuation
 Deep vacuum and dilution methods
 Commissioning checks
 Oil addition, removal and draining
 Balancing: measuring air volumes ,adjusting volume control and fan speed to get
desired air flow
